Opis:: The article presents selected results of the analytical work carried out in the Air Force Institute of Technology regarding the possibility of computer matching systems, digital display and analogue devices, both in the static states and in dynamic states while manoeuvring the aircraft. On the example of parameter of vertical speeds provided a method of matching the indications for the helicopter Mi-17-1V with built helmet-mounted display system of flight data SWPL-1 Cyclops (developed by the Air Force Institute of Technology and cooperating with analogue avionics). Adjusting the display of vertical speed achieved by an inertial element of first row, implemented programmatically in the computer graphics KG-1. On the other hand, method of adjusting of indications on the information presented in the helmet-mounted cueing system NSC-1 Orion (built in the Air Force Institute of Technology for helicopter W-3PL Capercaillie) and obtained from the integrated avionics system (with digital avionics), exemplified by magnetic heading (obtained from heading layout KCS-305) and geographic heading (obtained from inertial navigation system EGI-3000). Adjusting of indications realized by introducing amendments to the indications of the multifunctional monitor MW-1, translucent display HUD and helmet-mounted display WDN-1 (in the form of elected declination, implemented programmatically on the computer mission KM-1) and the amendments to the magnetic deviation (introduced periodically to heading compensator layout KCS-305).

Opis:: The following paper presents a method of determining the angular position of the pilot’s helmet based on the measurement of magnetic field components, artificially generated on board the aircraft (similarly to the helmet-mounted cueing systems of the F-16 aircraft). We presented a mathematical model, which describes determining of the angular position of the pilot's helmet, based on the measurement of the magnetic field components in various moments of powering orthogonally fixed magnetic coils. We also defined modelling capabilities of the helmet-mounted cueing system, which uses the magnetic method to determine the angular position of the pilot's helmet. It has been shown that the direction cosine matrix can be used for determining the angular position of the pilot's helmet, specified based on the matrix formed from the magnetic field components in various moments of powering orthogonal magnetic coils. The paper ends with an outline of simulation tests, which enable to identify the errors of the system, using such a method.

Opis:: The article presents the selected methods of identifying static and dynamic properties of the measuring paths to the extent necessary for the proper integration of on-board systems with the helmet-mounted flight parameter display system. It presents the methods of identifying static and dynamic properties of the WR-10MK on board variometer as one of more difficult identification elements. Its identification was carried out on the basis of the basic dependencies of the International Standard Atmosphere and the instruments construction’s parameters. It built a mathematical model describing the physical phenomena associated with vertical speed measurement. This model differs from the models found in the literature in terms of detail and description accuracy. On this basis, in the Simulink environment, it built a simulation model corresponding to its mathematical model. The non-linear model was the starting point for the construction of the linearized model based on the operator transmittance. The developed models were evaluated for errors of vertical speed’s dynamic indications. This allowed assessing the usefulness of the individual models for further works on ensuring the correlation of indications of the on-board variometer and the SWPL-1 helmet-mounted flight parameter display system. The presented simulation models include design details, as well as the characteristics of technological errors and disturbances of a stochastic nature. Another approach to the issue of identification is to use the characteristics provided by the manufacturer in the form of approximate characteristics of a module.

Opis:: The article presents selected results of the analytical work carried out in the Air Force Institute of Technology in the field of information visualization capabilities of helmet-mounted guidance and navigation in fighter aircraft MiG- 29. There is presented the SzCz-3UM headset system of target’s indication, currently used on-board of MiG-29, which is directly cooperating with the pilot during the combat flight. There was presented that the information from the onboard systems of this aircraft containing analogue devices must be computer-processed into digital form in order to present flight data in the helmet-mounted display system. However, MiG-29 aircraft, used in the Polish Air Force, are equipped with modern digital avionics (integrated avionics system) based on the MIL-1553B digital data buses, which gives the possibility of the new helmet-mounted imaging of flight parameters via the computer data processing from aircraft’s devices and on-board installations. To develop guidelines for the construction of the helmet-mounted system for the MiG-29, the SWPL-1 Cyklop flight data-displaying system was adopted (system developed in the Air Force Institute of Technology as avionics system modernization for Mi-17 military helicopters). There are discussed the main problems of scientific and specialist research positions used in the Air Force Institute of Technology to assess the accuracy of the selected equipment components of avionics systems and determine credibility of information provided to the pilot during the flight.

Opis:: The paper presents the structure and basic properties of the SWPL-1 helmet-mounted flight parameter display system, constructed for the Mi-17 helicopter with analogue systems and on-board instruments. It describes the basic components of the SWPL-1 system and on board components cooperating with the SWPL-1 system necessary to ensure the imaging system’s operation (including the ADU-3200 central unit for aerodynamic data and the GPS-155XL satellite signals receiver). It presents the architecture, the principle of operation, and the main constituents of the SWPL-1 helmet-mounted flight parameter system, as well as the standards of data transmission used in digital communication between the SWPL-1 system and on-board systems (installed on the Mi-17 helicopter). It describes the scope and manner of pilot and navigation data presentation as well as control of drive unit operation parameters in detail. It presents selected optimization methods for tasks executed in the helmet mounted system’s life cycle. The particular stages of the life cycle were described in detail, from the earliest stages of needs identification, through the analytic and conceptual phase, then the implementation stage, and ending with the operation stage. It introduces tasks for optimization and related methods into the process of creating the new system at every stage of its implementation. It presents one of the methods of multi-criteria optimization based on the experts’ assessment of choice of a variant of the helmet-mounted flight parameter display system’s hardware architecture in detail.

Opis:: The article presents the new built in Poland helmet mounted cueing system NSC-1 Orion with a magnetic method, dedicated to the multi-purpose helicopters W-3PL Gluszec. This system uses the magnetic field generated by the system of three mutually orthogonal electric coils. The principle of operation of this system is described and the method of determining the angular position of the pilot's helmet relative to the helicopter's cabin using the reference magnetic field and the directional cosines matrix are discussed. Electrical flat coils, constructed in the Polish Air Force Institute of Technology (AFIT), generating a magnetic field with curved symmetry axis characteristics, causing errors in determining the angular position of the pilot's helmet are shown. As a way to minimize these errors, an original proprietary algorithm for correcting the negative impact of the magnetic field curvature generated by the on-board system has been presented. Mathematical relations describing the presented correction process as well as selected results of simulation and experimental investigations in the area of inaccuracy of the "before" and "after" systems of applying the developed algorithm were given. Inaccuracies determined from computer simulations of the developed mathematical relations were compared with experimental data from magnetic field measurements using the integrated three-axis sensor ADIS-16405, used in the laboratory of the AFIT Avionics Division for helmet control of the angular position of the moving observation and sighting head and reflector-search light.
